Inventor: IKEDA YOSHI
IPC: C07D307/34
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To easily obtain an isoimide by reaction of a compound bearing carboxyl and amide groups in the identical molecule in the presence of a haloiminium salt and a basic substance. SOLUTION: This isoimide bearing an isoimido linkage of formula III in the molecule is obtained by reaction of a compound of e.g. formula I (R<1> is a divalent hydrocarbon, aliphatic group or aromatic group; R<2> is a monovalent hydrocarbon, aliphatic group or aromatic group), or between a compound of e.g. formula II (R<12> and R<13> are each a monovalent hydrocarbon, etc.) bearing an amido linkage and a carboxyl-bearing compound in the presence of a haloiminium salt such as N,N-dimethylchloromethyleneiminium chloride at 0.8-6 equivalent times the carboxyl group and a basic substance such as trimethylamine at 1-10 equivalent times the hydrogen halide formed by reaction between the haloiminium salt and the carboxyl group.

Title: Kick starting device for motor bicycle
Inventor: KURATA KOJI
IPC: F02N3/04
Filed: 1988-12-30
Abstract: PURPOSE:To prevent sudden start of a vehicle by making the extreme end of a locking shaft locked with the locking pin of a kick-drive gear, and making the kick-drive gear impossible to rotate even by operation of a kick lever at contacting of a rear wheel with the ground in the condition of receiving a stand. CONSTITUTION:When a rear wheel does not contact with the ground by projecting of a center stand 20, a locking shaft 21 is on the retreated position with a spring 23, and the extreme end is not locked with a locking pin 28. Therefore, when a kick lever fixed to a kick shaft 11 is kicked, a kick-drive gear 16 is rotationally moved, a crankshaft 1 is rotated, and an engine is started. Sequentially, when the center stand 20 is received, an abutting part 27 abuts on the lower end part of the locking shaft 21 and presses it, the extreme end part of the locking shaft 21 is locked with the locking pin 28, and rotation of the kick-drive gear 16 is restrained. Consequently, even if the kick lever 17 will be kicked, the kick-drive gear 16 does not rotationally move, and start of the engine is prevented.

Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To enable assembling of a small-sized semiconductor device of high performance at a low cost, by imparting heat dissipation capability to the surface of flexible composite, when a semiconductor chip is directly mounted on a circuit board. SOLUTION: Flexible composite 4 is fixed between a substrate electrode 5 of a circuit board 2 and a semiconductor chip electrode 3. The flexible composite 4 is formed by coating the surface of elastomer, elastomer powder filler, rubber, etc., with ceramics, and a heat dissipating layer 6 is formed. The flexible composite 4 fixes a semiconductor chip 1 to the circuit board 2, and dissipates heat generated by a semiconductor device during operation. The flexible composite 4 has flexibility and so can sufficiently exhibit thermal stress when the semiconductor is mounted. Thereby a small-sized semiconductor device of high performance can be easily assembled at a low cost.

Title: Liquid crystal display device with back light
Inventor: NAKAMURA MORITAKA
IPC: G09G3/18
Filed: 1993-12-27
Abstract: PURPOSE:To prevent irregularity in illuminance due to a flicker from being generated by equalizing the frequency of a back light illumination signal to the frequency of a vertical synchronous signal for driving a display part. CONSTITUTION:An integration circuit 10 consists of a diode D11, electric resistors R11-R14, a capacitor C11, and an amplifier A1. The integration circuit 10 generates a saw-tooth wave by inputting the vertical synchrorous signal VSY for module driving as original oscillation to the integration circuit 10. Then the generated saw-tooth wave and a back light illuminance control voltage are inputted to a comparator 20 consisting of an amplifier A2 to generate a rectangular wave synchronized with the signal VSY, and this rectangular wave is inputted to the back light for intermittent illumination. Thus, the irregularity in illuminance, etc., due to optical interference between a flicker component generated by the intermittent illumination of the back light and a flicker component of liquid crystal display driving can be prevented.

Title: Method for generating automatically adjacent zone information
Inventor: YOSHIMI MASAAKI
IPC: H04W24/08
Filed: 1995-12-20
Abstract: PURPOSE: To allow the system to trace automatically a revision of an adjacent base station attended with an environmental change or arrangement change in base stations by measuring an electric field strength of each received frequency signal and discriminating whether or not the signal comes from a base station in the same communication system when the electric field strength is more than a specified value. CONSTITUTION: A service area is divided into plural zones Zi, and each base station BSi is provided to each of the zones. A mobile station MS makes transmission reception with the base station BSi of a zone Zi and makes communication with other mobile station or stationary terminal equipment via the current base station BSi. In this case, an outgoing radio wave from other base stations in other zones than the current zone Zi is received and its electric field strength is measured, it is analyzed and whether or not a signal comes from a base station of a same communication system is discriminated. When the electric field strength is a specified electric field strength or over, and it is discriminated that the signal comes from the base station of the same communication system, the reception signal is discriminated to be a signal from surrounding base stations.  Thus, management control or artificial management via a central controller is not required.
